OK, as per hornetball's advice I changed the time to read in seconds, and then changed the header of that column to read "Time (s)" instead of "Timestamp (us)" (based on what I see in a csv that triple88a posted earlier in the thread). Still not right I'd guess, as it's showing me at >350hp when my airflow is only peaking at 23-24lb/min.

Hey Matt, plotted your data. Dynojet plot attached (used 3rd gear, stock wheel height and swagged weights at 2250# for car and 170# for driver). It looks pretty reasonable, but the curve gets wacky above 6500 or so. Makes me wonder if your clutch is slipping, although I'll occasionally get something similar at the end of a run -- probably some kind of VD trimming issue at the end of the data. Obviously, the stuff from 6500-on isn't real, but the rest of the curve is. Looks like ~220RWHP. Nice!

Damn you guys are faster than me haha...just did the same thing, trimmed the logfile and got the same results on the graph. And yeah hornetball, after getting my AFRs in line I started adding timing...will revisit that in the near future and keep bumping it up.

1.6, stock 5 speed and rear end; 3rd gear run in that file.

Thanks for plugging all that in…pretty much nailed the weights, too. How did you get the boost to show up in the lower graph?

Thanks Rick. And I can't yet log AFRs...need an input buffer for my ecu. But that's coming up sooner than later, and I'll be able to further refine them at that point as well. At the moment they are safe but not quite as smooth as I'd like. And after I found that my wastegate was loose last month I shimmed the ---- out of it, probably accounting for some of that boost spike. I may back it down a little and see if that helps smooth out the curve.

Hey guys, I've been trying to get this to work and for the life of me can't figure out what I'm missing. MS1 mspnp log, 3rd gear pull, once i can get it to work i'm going to work on getting some better pulls. As you can see my boost control sucks.

It gives the following error when I try to plot it:

"E101: Not all columns needed for calculations found.
REQUIRED COLUMNS: Time, RPM, Throttle Position
If your log does not contain these, the developer does not need your log."

Its a regular ms1 log which contains all of the above.

Please help me plot this and let me know what I need to do for future plots.

Did you do that? There's some good info on the first few pages of the thread. I had to export my logs as a .csv then do some trickery to get it to work. I don't know what to use to open .msl files or I'd try it myself.

I just dl'd Megalogviewer so I could see your file. Am I seeing your TP signal correctly? The steady, but low, value does not correspond to the jagged looking graph. That could be part of the problem with viewing the log in VD if so.
